The disclosure provides an HVAC data processing and communication network and a method of manufacturing the same. In various embodiments, the network includes a subnet controller configured to control networked devices via a data bus. The subnet controller is configured to be addressable over the data bus. An environmental sensor is configured to provide environmental data to the subnet controller, and is further configured to be addressable over the data bus independent of addressing the subnet controller. A user interface is configured to provide access by an operator to the network. The user interface is further configured to be addressable over the data bus independently of addressing the subnet controller and the environmental sensor.
